What is trailer arm?

A trailer arm, also known as a trailer axle, is the component of a trailer that is responsible for supporting the weight of the trailer and its cargo. It is typically made of steel and is attached to the trailer frame through a series of brackets and bolts.

Trailer arms come in various sizes and configurations depending on the type and size of the trailer. They may be straight or curved, and can have one or two axles. Single axle trailers typically have one trailer arm, while tandem axle trailers have two.

Trailer arms are important for maintaining stability and balance while the trailer is in motion. They allow the trailer to roll smoothly over bumps and uneven terrain, and help to distribute the weight of the cargo evenly across the trailer.

Proper maintenance and inspection of the trailer arm is essential for safe and efficient towing. This includes regularly checking for signs of wear and tear, such as rust or missing bolts, and ensuring that the trailer arm is properly lubricated and aligned.
